I have had a similar issue since iOS 9.2 with my iPhone 6s Plus. Safari randomly freeze when I open a link in the background. This issue doesn't appear every time, but does appear several times（<10） a week. I bought the 6sP this year and restored it from my local backup. Usually I have tons of tabs opened in Safari. Thus, I initially suspect this issue may related to those many tabs or some corruption in backup data. After upgrade to 9.3, I still have this issue. Not sure whether my problem is related to the problem discussed here, though they had similar behavior.
